Definitions

• a sorting machine in particular for small parcels
• the invention concerns a sorting machine of the type stated in the introductory portion of claim 1.
• the DE-AS 25 46 748 discloses a bucket elevator or con- veyor which is constructed in the same manner as is stated in the introductory portion of claim 1, although it is intended for bulk goods and not individual articles, such as small parcels and the like.
• the US Patent Specification 3 055 486 discloses a bucket conveyor of a similar type for transport of bulk goods from a supply station to one of a plurality of unloading stations.
• the object of the invention is to provide a sorting machine of the type stated in the opening paragraph, which requires little space and has a great sorting capacity, while the activation means used and their cooperation with the individual trays during emptying are simpler than in the first-mentioned prior art, and which enables the individual trays during emptying to be optionally pivoted with the opening in a forward direction (headwind) and in a rearward direction (tail wind).
• fig. 1 is a lateral view of one end of a sorting machine according to the invention.
• fig. 2 is a top view, on a larger scale, of the same end of the sorting machine of the invention.
• the sorting machine shown in the drawing contains a plu- rality of trays, la, lb, lc, Id, le, lg pre ⁇ ferably of aluminium and with a U-shaped bottom 2 and side members 3 and 4. These trays are at both sides pi- votally suspended from arms 5 which are secured at the top, at 6, to their respective ones of chains 7 and 8 driven, in synchronism and by the same drive motor (not shown), said chains being indicated in the drawing in broken lines.
• the chains 7 and 8 preferably consist of steel wires placed around a chain wheel at each end of . the sorting machine.
• the trays are pivotally suspended from arms 5.
• the suspension point 11 of the trays is disposed above the centre of gravity of the trays, so that their V-shaped bottom 2 usually assumes a horizontal position.
• a plurality of stationary chutes 14 is placed at even intervals in a machine frame (not shown), in which a corresponding number of levers 16 is secured, said levers being pivotable about a horizontal shaft 15.
• the levers 16 can be caused to assume an activated state by means of their respective pneumatic cylinders 17, during which the levers 16 associated with the upper path run are caused to engage the lower wheel 13 o.n each passing tray, as shown e.g. at the tray lb in fig. 1, and during which the levers 16 associated with the lower path run are caused to engage the upper wheel 12 on each passing tray, as shown e.g. at the tray If in fig. 1. Consequently, the trays lb and If in question are pivoted to empty their contents onto the chutes 14 disposed below,
• a plurality of levers 16a (only one is visible in the drawing) is provided, said levers 16a being pivotable about a horizontal shaft 15a and, seen in a vertical direction, disposed at the opposite side of the pivot axis 11 of the tray with respect to the first-mentioned levers 16, so that the trays can optionally be emptied both in the upper and the lower run of the path at one or the other side, depending upon whether a lever 16 or a lever 16a is activated and engages one or the other of the wheels 12 and 13.
• Activation means and projections may be arranged at both sides of the trays so that the trays are hit by activa ⁇ tion means simultaneously at each side.
